Application filed March 8, 1912. Serial No. 682,505.

To all whom it may concern Be it known that 1, CHARLES E. GILLI- LAND, a citizen of the United States, residing at Chicago, in the county of Cook, State of lllinois, have invented certain new and useful Improvements in Tobacco-Pipes; and I do hereby declare the following to be a full, clear, and exact description of the invention,

v such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in tobacco vpipes.

The principal object of the invention is to provide a novel mechanism for preventing the bowl of the pipe from becoming choked.

Another object of the invention is to provide a device for the purpose described which may be readily attached to or detached from the bowl of a pipe, and which, when in the latter position, will clearly facilitate the cleaning of said bowl.

A further object of the invention is to provide a device of the character described which is composed of a minimum number of parts, is therefore simple in construction, and is cheap to manufacture.

lVith these and other objects in View, the

invention consists in the construction and.

novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claim hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claim may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing: Figure 1 is a side elevation of a pipe constructed in accordance with my invention, Fig. 2 is a detail longitudinal sectional view through the bowl, Fig. 3 is a top plan view of the bowl, and Fig. 4. is a perspective view of the rotary scarper.

Like reference numerals designate corresponding parts in all the figures of the drawing.

Referring to the drawing, 5 designates a pipe bowl having the usual stem 6 extending from the lower portion thereof, said stein being formed with the usual bore 7. The

bottom of the bowl is detachably closed by a threaded plug 8 having a peripheral bead 9 formed thereon and projecting beyond the periphery of the bowl so as to facilitate the rotation of the plug. The upper face 8 of the plug is normally disposed below the bore 7 of the stem, and this plug is concentrically formed with a socket 8 in which is fitted the lower end of a tube 10, the upper end 10 of said tube being disposed above and in spaced relation to the top face 8 of said plug. Formed on the upper end of this tube is a circular perforated plate 11 of a diameter substantially equal to the interior diameter of the bowl. This plate forms a grate or support for the tobacco within the bowl, and is concentrically formed with an opening which registers with the tube 10.

A scraper 12 is mounted upon the plate 11 for rotation, and this scraper includes an operating stem 13 which projects through the tube 10 and beyond the outer face 8 of the plug. The projecting end of this stem is provided with a finger-piece 14 of any suitable construction for facilitating the rotation of the stem and consequently the rotation of the scraper.

In practice, when the tobacco chokes the perforated plate 11 to such an extent as to prevent the smoker from properly drawing the smoke through the bore 7 the scraper 12 is rotated by the operator through the medium of the finger piece 14. The rotation of this scraper will remove the tobacco from the plate 11, and thereby clear the perforations of the pipe so as to permit of a ready draft therethrough. When it is desired to clean the pipe, the operator bv grasping the rib 9 of the plug 8 may easily remove the latter together with the plate 11 and the scraper 12. These plates may then be readily cleaned, as will be readily understood.

What is claimed is:

A tobacco pipe including a straight cylindrical tobacco chamber, a closure for the lower end of the chamber, said closure being provided centrally with a socket opening in the chamber, a circular perforated disk having a centrally projected stud seated in and held and guided by the socket, a pin passed centrally through theclosure, a scraper bar secured to one end of the pin and slidable on the face of the disk and a finger piece secured to the other end of the pin outwardly of the closure whereby the device may be disassembled by removing the finger piece and drawing the pin, disk and bar through the mouth of the chamber.

In testimony whereof, I aflix my signature, in presence of two witnesses.

CHARLES B. GILLILAND.
